Make smarter decisions about buying, financing, and operating your vehicle.
Vehicle expenses are the second-largest household cost after housing for most families. From choosing the right financing terms to understanding the true cost of ownership, our auto calculators help you make decisions that save thousands over the life of your vehicle. Whether you are buying new, used, or considering an EV, the math matters.
Auto loans typically range from 36 to 72 months, with longer terms offering lower payments but higher total interest costs. A crucial concept is negative equity— when you owe more than your car is worth. Longer loan terms and low down payments increase the risk of being "underwater," making it costly to sell or trade in your vehicle. Our auto loan calculator shows you the trade-offs for different terms and down payment amounts.
A general rule is to keep total car costs (payment, insurance, fuel, maintenance) under 15-20% of your take-home pay. For example, on a $4,000/month take-home salary, aim for a total car budget of $600-800/month. Our auto loan calculator helps you determine what vehicle price fits your budget.
New cars lose 20-30% of value in the first year, then about 15% each subsequent year. By year 5, most cars are worth only 40% of their original price. This is why buying a 2-3 year old certified pre-owned vehicle is often the best financial decision — someone else absorbed the steepest depreciation.
Leasing offers lower monthly payments and a new car every 2-3 years, but you never build equity and face mileage restrictions (typically 10,000-15,000 miles/year). Buying costs more monthly but is cheaper long-term — once the loan is paid off, you own a free-and-clear asset. Buying and holding for 8-10 years is generally the most cost-effective approach.
Beyond the purchase price, car ownership includes insurance ($1,200-2,400/year), fuel ($1,500-3,000/year), maintenance ($500-1,000/year), registration and taxes ($200-500/year), and depreciation. The average American spends $10,000-12,000 per year on total vehicle costs.
EVs have higher upfront costs but significantly lower operating costs — electricity costs about $0.04/mile vs $0.15/mile for gas. With federal tax credits up to $7,500, the break-even point for many EVs is 3-5 years. Our fuel cost calculator can help you compare the total cost of ownership.
